CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 543,921, dated August 6, 1895,-

Applioation filed February 13, 1895. Serial No. 538,198. (No model.)

in a position to receive the link. Fig. 2 is a similarview illustrating the position of the parts while the link is being inserted. Fig. 3 is a similar view showing the position of the parts after the link has been received by the coupler. Fig. 4 is an end elevational View.

This invention relates to a new and useful improvement in car-couplers of that class which are especially adapted to hold the link in a horizontal position. The construction involves the use of the pivoted pin, a pivoted weight located to the rear of thepin, and a dog which is in the path of the pivoted pin for holding the same in an upright position after the link has been inserted, all as will hereinafter be described, and afterward pointed out in the claim.

In the drawings, A indicates a draw-head which is formed with an opening in its top, in which the pivoted dog is received. The draw-head is also provided at its front end with lips A and A, which are grooved about 3 5 their middle portion to afford operatingspace for the pivoted dog and pin, respectively.

B indicates apivoted dog, the front face or nose of which is preferably formed inclined,

0 the rear face of the long member having at-l tached thereto an eye or hook whereby the same may be operated, which long member is.

also formed with an inclined end which cooperates with a corresponding incline in the 4 5 draw-head. This permits the dog to be raised or the nose forced back, as shown in Fig. 2;

but when the pin is in engagement therewith the dog is in a locked position, as shown in Fig. 3.

O indicates apivoted pin, the forward memher of which rests in the groove between the lips A" when the coupler isin an unlocked position, as shown in Fig. 1. The forward end of this member is formed with an inclined face, which strikes the nose of the dog in its path when being operated, and riding past said nose is locked therebehind, as shown in Fig. 3. O is the other memberof the pivoted pin, and is arranged at about right angles to the member just referred to. When the link is inserted it is elevated, depressed, .or guided by the lips A A" to contact with the member O of the pin, which it forces backward, as shown in Fig. 2, until the front member of the pin is behind the nose of the dog, when the link is locked.

To hold the link in a horizontal position, to obviate handling by the brakeman, I pivot in the rear of the opening in the draw head a block D, which is recessedat its forward under side, permitting the member O'of the pin to operate therein. The front end of this block is formed with curved faces, immediately behind which the sides of the block are recessed, as at d, to more readily receive the link.

The operation of the device is clearly illustrated in the drawings, and a detailed description need not be given here.

Attention will be called to the fact that the So forward end'of the block D .rests upon the rear curved face of a member ()"of the pin, so that when the pin is actuated, as shown in Fig. 2, the block D is raised to receive the link under its forward end. When the piv- In a car coupler, the combination with a 5 suitable draw-head, a pin pivoted in the lower forward portion of the head, said pin com prising two members, 0 and O, a dog B ar- 10 bear upon the link for holding it in ahorizontal position, and with recesses (Z behind said projections, to receive the link; substantially as described.

In testimony whereof I hereunto affix my signature, in presence of two witnesses, this 1';
